Combustion heat release models of biodiesels

Fossil fuels such as standard gasoline and diesel fuel are the most important source of energy for our society today, providing the bulk of global energy requirements for transportation, construction, heating, and agriculture. Many new developments in technology have made alternative sources of energy more economically feasible including advances in solar, wind, geothermal and nuclear energy. It is a domestic, clean-burning, renewable liquid fuel that can be used in compression-ignition engines instead of petroleum-based diesel with little or no modifications. Biodiesel blends are more commonly used than pure B100 fuels. The main reason for this is that running 100% biodiesel sometimes requires modifications to the engine, due to the higher content of alcohol present in biodiesel.
